Craftsman 921.16474 Air Compressor User Manual


 
ELECTRICAL WIRING
Refer to the air compressor's serial label for the unit's voltage
and amperage requirements.
Use a dedicated circuit
For best performance and reliable starting, the air
compressor must be plugged into a dedicated circuit, as
close as possible to the fuse box or circuit breaker. The
compressor will use the full capacity of a typical 15 amp
household circuit. If any other electrical devices are drawing from
the compressor's circuit, the compressor may fail to start. Low
voltage or an overloaded circuit can result in sluggish starting that
causes the motor overload protection system or circuit breaker to
trip, especially in cold conditions.
NOTE: To handle the initial electrical toad of starting the air
compressor, a circuit breaker is recommended. If the air
compressor is connected to a circuit protected by a fuse, use dual
element time delay fuses (Buss Fusetron type "T" only).
EXTENSION CORDS
NOTE: Avoid use of extension cords.
For optimum performance, plug the compressor power cord
directly into a grounded walt socket. Do not use an extension cord
unless absolutely necessary. Instead, use a longer air hose to
reach the area where the air is needed.
If use of an extension cord cannot be avoided, the cord
should be no longer than 50 feet and be a minimum wire size of
12 gauge (AWG). Do not use a 16 or 14 gauge extension cord.
Use only a 3-wire extension cord that has a 3-blade
grounding plug, and a 3-slot receptacle that wilt accept the plug
on the product. Make sure your extension cord is in good
condition. An undersized cord will cause a drop in line voltage,
resulting in loss of power and overheating. The smaller the gauge
number, the heavier the cord.
GROUNDING INSTRUCTIONS
FOR CORD-CONNECTED MODELS:
This product should be grounded. In the event of an electrical
short circuit, grounding reduces the risk of electric shock by
providing an escape wire for the electric current.
This product is equipped with a cord having a grounding wire
with an appropriate grounding plug. The plug must be plugged
into an outlet that is properly installed and grounded in
accordance with all local codes and ordinance.
product is properly grounded. Do not modify the plug provided; if
it will not fit the outlet, have the proper outlet installed by a
licensed electrician.

If repair or replacement of the cord or plug is
necessary, do not connect the grounding wire to
either fiat blade terminal of the plug. The wire"
insulation having an outer surface that is green with
or without yellow stripes is the grounding wire.
This product is for use on a 115 or 230 volt circuit. A cord
with a grounding plug, as shown here, shall be used.
Make sure that the product is connected to an outlet having
the same configuration as the plug (see Fig. 5). No adapter
should be used with this product.
Check with a licensed electrician if the grounding instructions
are not completely understood, or if in doubt as to whether the
